Buy or hire the FlexiSand 1.9 if...
A single-disc rotary sander used for buffing, screening and light sanding rather than heavy stock removal, which is why floor contractors keep one alongside a belt or drum sander rather than instead of one. Its 407mm disc and 1.9kW motor put it in the same bracket as other single-phase rotary buffers sold through UK flooring trade counters.

Buy or hire the Hummel if...
The classic belt sander used to strip and refinish wood floors, in production since 1969 and still the reference machine flooring contractors and DIY renovators reach for. UK hire listings sometimes attribute it to Bona, the abrasives and finish brand, rather than its actual maker Lagler.
